“…Davies ( 1959 ) and Booth ( 1978 ) found signifi cantly more mite larvae on female dipterans but Booth attributed this greater load to the larger size of the female fl ies. Gledhill et al ( 1982 ), on the other hand, found little evidence of preference for female black fl ies over males as hosts for Sperchon larvae. Mitchell ( 1967 ) and Robinson ( 1983 ) both found that male odonates were more commonly parasitised than were females.…”

“…Davies ( 1959 ) had a different opinion and felt it was possible that some chemical factor, released as the pupal skin splits, stimulates larval Sperchon (Sperchontidae) to congregate near emerging adult black fl ies. Gledhill et al ( 1982 ) studied Sperchon setiger larvae in England and saw that the mites would enter the pupal cases of blackfl ies long before the insects were ready for ecdysis. This early colonisation appears to refute Davies' concept of a chemical cue leading to the congregation of mites at times of mass emergence.…”

To most non-biologists, a 'mite' is an almost invisible creature that lives in the carpet and gives you asthma or that burrows in your skin to produce socially unacceptable scabies. Cat owners may curse the ear mites that infest their pets and those who know that ticks are mites may mention Lyme Disease. Such medically important associations between mites and mammals are discussed in most parasitology texts, and mites associated with human diseases are discussed in our Chap. 10 ; therefore, in this chapter we cover ticks and other human-and livestock-associated mites superfi cially, concentrating instead on lesser known relationships between mites and the animals they use for room and board. These associations are not always negative; in fact, many seemingly parasitic mites have no impact on their hosts or may even be benefi cial (see section " Mutualism ", below).One of the recurring themes of this book is that mites live in the most astonishing places. This is particularly apparent among animal-associated acarines. A complete list of associations between mites and other animals would occupy an entire book but to whet the reader's appetite we have provided Table 9.1 , where we list the associations that acarologists use to shock jaded students or to start conversations at dull parties. After perusing this list many will be compelled to exclaim, 'What's a mite doing there?' or 'How did a mite get there?'. The fi rst question is a proximate one -what is the ecology of the symbiotic mite? -and the second an ultimate one -what evolutionary history and selective pressures have resulted in this association? In the fi rst section of this chapter we discuss the ecological terminology dealing with symbiosis and then outline some major hypotheses about how different symbioses may evolve. The next two sections discuss the life histories and behaviour of mites associated with invertebrates and vertebrates respectively and the fourth section surveys the diverse effects that parasitic mites have on their hosts. Finally, the last section addresses the topic of coevolution between hosts and symbionts from an acarine point of view.

“…DAVIES (1959) reported the parasitism of black flies by larval water mites, mainly of the genus Sperchon. GLEDHILL et al (1982) also reported some aspects of the host-parasite relationship between adult black flies and larvae of Sperchon setiger THOR 1898 in a small stream. MAR-TIN (2004) reviewed the specificity of attachment sites of larval water mites (e.g., Sperchon, Protzia and Hygrobates) on their insect hosts, Chironomidae.…”

“…MAR-TIN (2004) reviewed the specificity of attachment sites of larval water mites (e.g., Sperchon, Protzia and Hygrobates) on their insect hosts, Chironomidae. SMITH and OLIVER (1976) reported most Sperchon larvae attached to some chironomid species on the thorax (including cervix) and abdomen, whilst GLEDHILL et al (1982) reported that they attached to three species of Simulium (black flies) in the ventral neck region. Numerous larvae will often parasitize a single host specimen but parasitism of a host individual by larvae of more than one species of water mite occurs regularly (SMITH et al, 2001).…”

“…Water mites are one of the few groups of aquatic organisms that achieve dispersal through parasitism, the larval stages of most species being parasitic for some time on aquatic or semiaquatic insects (GLEDHILL et al, 1982). RACK (1976) reported the parasite infection of Limoniinae (Tipulidae) by water mite larvae in the Allgäu (northern border of the Alps).…”

This is the first report of parasite infestation of Tipulidae by water mite larvae in the middle reaches of a river in Japan. Forty-four species of adult crane flies were identified. The most abundant species was Antocha (Antocha) bifida ALEXANDER 1924 with 22 204 individuals (76.5% were male). Some 2113 individuals (9.5%) were parasitized by water mites, viz., Sperchon plumifer THOR 1902 (maximum: 40/host, mean value: 3.5 ± 2.5/host). 73.1% of S. plumifer larvae were attached to the abdomen. Many S. plumifer larvae parasitized A. bifida adults from late May to early July, but after a small flood, few S. plumifer larvae were collected. Floods have a major impact on both the A. bifida population and on its parasite, the S. plumifer larval population. IntroductionThe hydrachnellid water mite species pass through an ectoparasitic larval stage on insect hosts of various orders (reviewed by SMITH and OLIVER, 1976). Recently, studies on many aspects of the host-parasite relationships (from genes to communities) between aquatic insect adults and larvae of water mites have been reported (PROCTOR, 2004). In contrast, in Japan, such reports concerning the host-parasite relationship are very rare. Although IMAMURA (1950), andMITCHELL (1967) reported on water mites parasitic on damselfly and stonefly, little is known about the host-parasite relationship between water mite larvae and aquatic insect adults. In addition, these studies have focused on small streams or upper reaches of rivers.Crane flies, one of the largest groups of aquatic insects, occur in most types of freshwater habitats such as springs, streams and seepage areas, rivers, lakes, ponds, marshes and temporary pools (reviewed by ROGERS, 1933). They have been particularly successful in subdividing resources within these habitats (reviewed by PRITCHARD, 1983). Many studies of the seasonal abundance and growth rates of crane flies in relation to environmental factors (water temperature, dissolved oxygen concentration, and food abundance) have been conducted in lentic/lotic habitats LIVINGSTON and GELHAUS, 1993;PRITCHARD, 1983;WINTERBOURN, 1996). However, there have been few previous reports on the seasonal changes in emerging adult crane flies in the rivers of Japan, and the parasite infestation of adult crane flies by water mite larvae has either been overlooked, or no rele-
